### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    These Breakers Are GREAT!
  

*by T***N on Reviewed in the United States on March 14, 2019*

This thing is awesome! I have factory breakers installed in my boat but have never seen them like this before. I had a customer come to me to get light bars and an auxiliary fuse block added to his 2019 Polaris Ranger. While the fuse block had its own fuses I wanted to add an inline fuse to the fuse block as well since the power wire would be running just above the plastic skid plate near the drive shaft (where all the factory wires run)  and I knew he would be using this in the West Texas Hill Country with a ton of sharp and jagged rocks. So in case anything should happen while out in the middle of no where I wanted to fuse this main power wire close to the battery. While searching for fuses I found this breaker and immediately thought this would be a good idea to be able to fix an issue and reset out on a trail instead of having to carry spare fuses or even possibly having to order one of the fuses online and waiting several days for it to show up. These are awesome and I will definitely be purchasing these for more jobs as they come up.

    Performed just as described.
  

*by J***T on Reviewed in the United States on September 16, 2019*

The unit seems like it's good quality, and it was easy to install.  I can't vouch for the waterproofness, but that looks good visually.  I use the push button whenever I need to service my system for any reason.  To re-connect you just flip back the little yellow lever.  Nice!

*by R***H on Reviewed in the United States on March 14, 2021*

Sheerness and thickness of a circuit breaker? Amazon really needs to check the adjectives they use for item descriptions. Anyhow, fast shipping and it should work fine on the wiring for my new trolling motor.
